Product Details

The Gibson 66500 Cat-Back Dual Extreme Exhaust System delivers aggressive dual-exit performance in a complete bolt-on package built from heavy-duty stainless steel. Dyno-tuned and tested for real street gains, this system is engineered to produce an average of 15–20 horsepower improvement while giving your truck a commanding, heads-turning exhaust note.

The dual outlets exit behind each rear tire at an aggressive angle, combining bold visual impact with a powerful, deep exhaust tone. Gibson's baffled and chambered muffler design minimizes interior drone while maximizing sound quality — no internal packing means consistent, long-lasting performance. All hardware and factory-style hangers are included for a straightforward, no-weld, bolt-on installation.
